SPECIFICATION fornrngpart ozt Letters Patent No. 522,440, dated July 3, 1894. App'lication fiidvitimafy 2e', 1894. saai 110.497.780. (No model.)

` To a/ZZ whom vit may concern.-

-Be it known that I, .T oHN H.ITYRRE`I`.L,` of.

New York city, inthe county and State of New York, have invented a new and Improved Conduit Electric Railway, ot' which the following is a full, clear, andexact description.

My invention relates to improvementsl in that class of electric railways in which the mam conductor or line wire is arranged infa condult beneath the road bed; and the'obj ect of my invention is to produce a railway of this class having theconduit constructed and arranged 1n such a manner that easy contact v may be made with the line wire and that the line wire may be perfectly protected and insulatcd, also to providev means `for easily shifting the trolley from side to side, and further, to construct the apparatus so that the trolley may be easily disconnected and that at the same time the brakes may be applied,-

` thus enabling the car toy be easily stopped.

To these ends my invention consists of certaln features o fconstruction and combinations of the same, which will be hereinafter described and claimed.

Reference is to be had to the accompanyingV drawings, forming a part ofthis specification, 1n whlch slmilar figures o f reference indicate corresponding parts in all the views.

Figure 11s a. longitudinal section of 'uit rau-V Way and the car thereon, the section being taken on the line 1-1 of Figs. 2 and 5. Fig. 2 1s a cross section on the line 2--2 ofFigsil Fig.- 3 is cross section on the line 3-:3 of Flg. l. Fig. 4 is a broken side elevation, partly in section, of the clamp which supports the line 'wire' and conductor; and Fig. 5 is a detail plan view of thel car truck and the arrangement of the trolley arm and brake mech' anlsm. Fig. 6 is av longitudinal section, o n the line 66 of Fig.. 5, of the car truck. Fig.A 7 is a broken side elevation of the trolley and its supporting arm. Fig.` 8 is asectional plan ofthe trolley and support; andFig. 9 is '.a

broken -vertical section on the Vline 9;;9 ofv Fig. 7.

The railway isprovidedfwith a conduit comprising a troughlikestruc'tiirej 10, which] is preferably of metaland 'which has base ianges 1'1 adapted to besecured to support? ing sleepers 12, or equivalent supports, and above the conduit are transverse beams 13 4which are preferably of .metalA and which are arranged between the track rails 13, the beams being separated in the center so as to 4forni the'longitudinal slot 14fin the topof .the conduit, through which slot extendsthe trolley arm 15. The top of the lconduit is covered in any suitable mannerv and it is braced by diagonally arranged braces 16 which are Vbolted to the beams` 13 and tothe sides of the conduit.

The upper portion of the conduit adjacent to the slot 14 is inclined preferably, as shown at 1-7 ink Fig. 3, and on the opposite side of the slot 14 is a vertical and longitudinal guard platel8 which hangs down in the conduit and yclamping plates -21, as illustrated in Fig.

3, althoughthe wire may be continuous, if desired. l u

` The wire 2O is supported in an inverted Ulshaped clamp 22, which extends the full length of 'the wire and which is arranged with its open side down and with its edges entering grooves in the upper portion of the wire, which is oblong in cross sectionand grooved on the sides, as shown clearly inFig. 3. The edges of the clamp are fastened against the wire'` by means of cross bolts 2'3 which compress the sides of the clamp. The wire 2O is insulated in the clamp, as'shown in Figs. 2 and 3 and the clamp andupp'er portion of the wire 'are embedded 'in insulating material which fills the body portion of the supporting tube 24, this tube being of aV generally cylindrical shape and having its under 'side open so lthat the bare Wire may project from it, thisfpart of the wire being shielded 'by diverging anges 25 on the lower edges of the hanger. The supporting tube is continuous and is, for convenience, made up in sections and the sections are preferablyunited, as illustrated in Figs. 1 and 3, by means of couplings 27 which comprise plates of the same general shape as the supporting tube, so as to form.

continuations of it, the plates having meeting flanges 28 at the top, which are bolted together, as shown in Figs. l and 3. The supporting tube may be supported in any convenient way, but, as illustrated, it is fastened at the top to the cross beams 13, as shown at 26 in Fig. l.

The line wire 2O is half round, on its lower face, and on it runs the trolley wheel 29, which is of conducting material and is held between insulating washers 30 and on a shaft 31, which is also of conducting inaterial,and is held in a support 32, the shaft connecting, as shown at 33, with a conducting shaft 34 which is arranged at right angles to the shaft 31 and is held in insulating material 35 at the lower end of the trolley arm 15. The trolley wheel and the support 32 swing in the lower end of the trolley arm 15, the shaft 34 serving as the journal for the trolley. This arrangement enables the trolley to be swung from one side to the other so as to Iit against a wire hung on either side of the slot 14.

The trolley arm 15 consists of a vertically movable frame 36, which moves in slideways 37 on the truck frame 38 on which is mounted the car 39. On each side of the support 32 are conducting collars 40 which (it close on the shaft 34 and these contact collars or washers connect with wires 41 which are adapted to connect with the motor on the car in the usual way.

0n the shaft 34 is a beveled gear wheel 42 which meshes with a pinion 43 on the lower end of a vertical shaft 44, which shaft is hung on the frame 36 and has, at its upper end, a beveled pinion 45 meshing witliasimilar pinion 46 on a shaft47, which is mountedin suitable supports and extends laterally from the truck frame 38, as shown best in Fig. 5, and if the trolley is-to be shifted from one side to the other, a wrench may be applied to the shaft 47 and the shaft turned, which movement, by means of the gear mechanism just described swings the support 32 and the trolley wheel 29.

The trolley arm or frame 36 is slotted in the middle and is provided with a cross sprin g 4S, see Fig. 1, which is adapted to be engaged on its under side by a cam 49 on the trans verse shaft 50, which is mounted in suitable supports on the truck frame and consequently, by turning the shaft and cam, the trolley frame may be raised or lowered. The shaft 50 is provided with cranks 51 which are pivoted to rods 52 extending longitudinally beneath the car, to the ends thereof, where each is pivoted to the lower end of a lever 53 extending upward through the car platform and moving opposite a quadrant 54 to which the lever may be fastened by the usual hand latch. This arrangement enables the trolley to be raised or lowered by simply moving one of the levers 53.

The shaft 50 extends through suitable supports 55, near opposite ends of the truck frame, and on the ends of the shaft are elliptical cams 56 against opposite sides of which press the curved plates 57 of the brake rods .58 which are hung in suitable guides 59, see F ig. 6, and the rods carry brake shoes 60 which are adapted to press against the wheels 61. The rods 58 extend through spring cases 62 on the truck frame, in which cases are spiral springs 63 pressing against studs 64 on the brake rods, and the pressure of these springs normally retracts the rods and holds the brake slices off the car wheels.

When the brakes are to be applied, one of the rods 52 isl pulled by means of the lever mechanism described, and this oscillates the shaft 50 and turns the cams 56 so as to spread the plates 57 and force the brake shoes against the car wheels. At the same time the oscillation of the shaft 50 swings the cam'49 from beneath the spring 48, thus permitting the trolley arm to drop and forcing the trolley wheel 29 oif the line wire 20, thus breaking the motor circuit at the saine time thcbrakes are applied and, of course, this permits the brakes to be set with much greater effect than they could be if the motor circuit were not broken. 4

I-Iaving thus described my invention, I claim as new and desire to secure by Letters Patent* 1. The combination, with the supporting tube having a longitudinal opening, and thc insulating material in the said tube, of acontinuous clamp embedded in the said insulating material, and a line wire held by the clamp with its outer face projecting beyond the insulating material, substantially as described.

2. The combination, with the slotted conduit, of the metallic supporting tube having diverging iianges at its lower side, an open bottomed clamp imbedded in insulating material within the supporting tube, and the line wire held by the clamp and projecting from the insulating material, substantially as described.
